The distance to this star can be estimated from its annual parallax shift of 6.8168 0.1430, which yields a separation of roughly 480 light years. It is moving nearer with a heliocentric radial velocity of −8 km/s, and will make its closest approach in around 6.1 million years at a distance of about 128.36 pc ly flip on 3. The star is faintly visible to the naked eye with an apparent visual magnitude of 5.08. This is an ordinary B-type main-sequence star with a stellar classification of B3 V. It is just 11 million years old with a high projected rotational velocity of 115 km/s. The star has an estimated 6.1 times the mass of the Sun and around 3.9 times the Sun's radius. It is radiating 573 times the Sun's luminosity from its photosphere at an effective temperature of 15,648 K.
